YANG Search return 500 to all queries; YANG impact analysis return unknown error

Hello,

When I use the YANG Search function today(15/10), towards all inputs the website return:
```
Http failure response for https://www.yangcatalog.org/api/yang-search/v2/search: 500 OK
```

For the YANG impact analysis, for all queries the website return:
```
The application has encountered an unknown error.
